Where slowly dripping saturated water exits limestone joints or cracks and contacts with the air inside the cave, some of the Ca(HCO 3) 2 in solution will precipitate back into CaCO 3. Stalactites on the cave ceiling are formed slowly by continuous CaCO 3 precipitation. This has nothing to do with evaporation as the relative humidity in caves ...

As time passed the limestone, which is permeable and soluble, was eroded by water. Weak carbonic acid in rainwater, reacting with the chemicals in the rock, dissolved and eroded away the limestone as the water filtered into the underlying depths of sediments. Large hollow solution cavities were formed in the limestone in this way.

It the process by which the rocks are dissolved when exposed to rainwater. Limestone and rock salts are particularly the rocks that form solvent solutions when exposed to rainwater, surface waters, or even ground water. Upon dissolving, the minerals in the rocks become ion solutions in the water which are then washed away.
